Everyone here has a write-up, drawn from the same records that explain the names while you read the text.
Solomon
King of Israel, before the splitDavid's son, who asked God for wisdom and received riches and fame besides. He built the great temple in Jerusalem and his reign was Israel's golden age of peace. But his seven hundred wives turned his heart to their gods, and for that idolatry God foretold the kingdom would be torn in two after him.
1 Kings 31 Kings 61 Kings 11Study → Rehoboam
King of JudahSolomon's son and heir, who threw the kingdom away in a sentence. Asked to ease his father's heavy taxes, he spurned the elders and told Israel he would scourge them with scorpions where Solomon used whips, so ten tribes tore away under Jeroboam. In his fifth year Shishak of Egypt stripped the temple of Solomon's gold.
1 Kings 121 Kings 14:21-312 Chronicles 12Study → Asa
King of JudahA reformer whose heart was fully the LORD's all his days. Asa smashed the foreign altars and sacred pillars, and would not spare even his grandmother Maacah: he deposed her as queen mother and burned her obscene idol. His one late failure was buying Aram's help instead of trusting God, and jailing the seer who rebuked him.
1 Kings 15:9-242 Chronicles 14-16Study → Jehoshaphat
King of JudahA God-seeking king who sent Levites through the towns to teach the Law. Facing a vast coalition, he set singers ahead of his army to praise the LORD, and the enemies turned on each other before a sword was drawn. His weakness was alliance: he bound Judah to wicked Ahab by marriage and nearly died in Ahab's war.
1 Kings 222 Chronicles 17-20Study → Jeroboam I
King of IsraelThe first king of the breakaway north, once Solomon's own officer, raised up by Ahijah's torn-cloak prophecy. Afraid his people would drift back to Jerusalem to worship, he cast two golden calves, one at Dan, one at Bethel, and said, 'Here are your gods, O Israel.' It became 'the sin of Jeroboam,' the idolatry every northern king after him would repeat.
1 Kings 11:26-401 Kings 12:25-331 Kings 14Study → Omri
King of IsraelA powerful soldier-king who bought the hill of Samaria and built the northern capital there. So dominant that Assyria long called Israel 'the house of Omri,' yet Scripture spends only a few verses on him, because he did more evil than every king before him, and fathered a worse son.
Ahab
King of IsraelThe most infamous king of Israel, who 'sold himself to do evil.' He married Jezebel of Sidon, built a temple to Baal in Samaria, and let her murder Naboth for a vineyard. Against him God raised Elijah, the three-year drought, the fire on Mount Carmel, the still small voice. Ahab died from a random arrow at Ramoth-gilead, and dogs licked his blood just as the LORD had said.
1 Kings 16:29-331 Kings 17-22Study → Abijah
King of JudahRehoboam's son, who reigned only three years. He committed the same sins as his father, yet when he faced Jeroboam's larger army he called on the LORD and won a great victory for Judah.
1 Kings 15:1-82 Chronicles 13Study → Nadab
King of IsraelJeroboam's son, who walked in his father's sins. While besieging a Philistine town he was assassinated by Baasha, who then destroyed every heir of Jeroboam, just as the prophet Ahijah had foretold.
Baasha
King of IsraelHe murdered his way to the throne and reigned twenty-four years, fortifying against Judah until Asa hired Aram to break him. For his evil, the prophet Jehu foretold that his house would fall like Jeroboam's, and it did.
Elah
King of IsraelBaasha's son, who reigned two years. While drinking himself drunk in a servant's house, he was struck down by Zimri, one of his own officers, ending Baasha's line.
Zimri
King of IsraelThe shortest reign in Israel, seven days. Having killed Elah and all of Baasha's house, Zimri found the army had crowned Omri instead. When Omri took the city, Zimri set the palace on fire and died in the flames.
Ahaziah
King of IsraelAhab's son, who served Baal like his parents. Injured falling through an upper lattice, he sent to consult Baal-zebub of Ekron rather than the LORD, and Elijah met his messengers with word that he would not rise from his bed.
Joshua
Successor to MosesMoses' assistant and one of the two spies who came back from Canaan saying it could be taken. He led the crossing of the Jordan and the conquest, and at the end of his life made the whole nation choose openly whom they would serve.
Exodus 17:8-16Exodus 33:11Numbers 13-14
Bathsheba
Wife of David, mother of SolomonThe woman David saw from his roof, in an episode the text presents as the king's sin rather than hers, and whose husband Uriah he had killed to cover it. She later secured Solomon's succession, and Matthew lists her in the genealogy of Jesus.
2 Samuel 11-121 Kings 1Matthew 1:6
Nathan
Prophet in David's courtThe prophet who brought David both the covenant promise of an everlasting throne and, later, the parable of the poor man's lamb that trapped the king into condemning himself.
2 Samuel 72 Samuel 12:1-151 Kings 1
Jezebel
Queen of IsraelA Sidonian princess married to King Ahab, who brought the state sponsorship of Baal into Israel, hunted the prophets of the LORD, and arranged Naboth's judicial murder over a vineyard. Her name became a byword, used as such even in Revelation.
1 Kings 16:311 Kings 18-212 Kings 9:30-37
Elijah
Prophet to IsraelThe prophet who confronted Ahab and Jezebel head on: three years of drought at his word, fire on the altar at Carmel, and then a collapse into despair under a broom tree. He did not die but was taken up in a whirlwind, which is why later Jewish expectation looked for his return before the day of the LORD.
1 Kings 17-192 Kings 2Malachi 4:5
Elisha
Prophet to IsraelElijah's successor, who asked for a double portion of his master's spirit and got it. His ministry runs through ordinary households as much as royal courts: a widow's oil, a borrowed axe head, a foreign general's skin, a poisoned pot of stew.
1 Kings 19:19-212 Kings 2-13
Hazael
King of AramAn Aramean official who smothered his own king and took the throne, exactly as Elisha had wept and foretold. He then spent decades grinding down Israel, and 2 Kings says he did to them what Elisha had seen him do.
1 Kings 19:152 Kings 8:7-152 Kings 13:22
Ahijah
Prophet of ShilohHe met Jeroboam on the road, tore a new cloak into twelve pieces, and gave him ten, announcing the division of the kingdom before it happened. Years later, blind and old, he delivered the verdict on the dynasty he had helped begin.
1 Kings 11:29-391 Kings 14:1-16
Micaiah
Prophet to AhabThe prophet Ahab hated because he never said anything good. Summoned alongside four hundred court prophets all promising victory, he mocked their message, then told the truth and was jailed on bread and water until the king should return in peace. The king did not return.
1 Kings 222 Chronicles 18
Joab
David's commanderRuthless, effective, and impossible to control. He murdered rivals, killed Absalom against direct orders, and spoke to David more bluntly than anyone else dared, including telling him he was destroying his own army with his grief. David never managed to be rid of him and left the problem to Solomon.
2 Samuel 3:22-302 Samuel 18-191 Kings 2:5-6
Barzillai
The court and its servantsThe stewards, counselors, recorders, bodyguards, and hangers-on who fill the books of Samuel and Kings. Barzillai the Gileadite fed David's army in exile and then refused to come to the palace because at eighty he could no longer taste what he ate.
2 Samuel 15:19-222 Samuel 16:1-42 Samuel 17:5-16
Shishak
Foreign kings and their officersThe rulers outside Israel who invade, extract tribute, or grant permission. Shishak of Egypt stripped the temple in Rehoboam's fifth year and left a relief at Karnak listing the towns he took. Necho killed Josiah at Megiddo. Tiglath-pileser III began the Assyrian deportations.
Genesis 14:1-171 Kings 14:25-262 Kings 15:29
Hananiah
The prophets who opposed the prophetsScripture names the men who prophesied against its own prophets, and it does not present them as obvious frauds. Hananiah broke the wooden yoke off Jeremiah's neck in the temple and announced that Babylon would fall in two years. Zedekiah son of Chenaanah made iron horns and promised Ahab victory, then struck Micaiah across the face.
1 Kings 22:11-24Jeremiah 20:1-6Jeremiah 28:1-17
Jehu
Prophet, son of HananiA prophet who carried the word against Baasha of Israel, and who later met King Jehoshaphat of Judah coming home from the battle where Ahab died with a blunt question: should you help the wicked and love those who hate the LORD?
1 Kings 16:1-7
Obadiah
Ahab's stewardThe official in charge of Ahab's household, who feared the LORD greatly and hid a hundred prophets in two caves during Jezebel's purge, feeding them bread and water. Elijah sends him to announce his return, and he protests that it will get him killed.
1 Kings 18:3-16
Amnon
Sons of DavidTwo of David's older sons, both of whom came to ruin. Amnon raped his half-sister Tamar and was killed two years later by her brother Absalom. Adonijah declared himself king while David was dying, was spared by Solomon, and was executed after asking for David's nurse as a wife.
2 Samuel 13:1-291 Kings 1:5-531 Kings 2:13-25
Amasa
The commander Joab killedDavid's nephew, made commander of Absalom's rebel army and then, after the revolt collapsed, offered Joab's job as a gesture of reconciliation. Joab took his beard as if to kiss him and stabbed him with a sword held in the other hand.
2 Samuel 17:252 Samuel 19:132 Samuel 20:8-12
Benaiah
Captain of the guardOne of David's mighty men, remembered for killing two Moabite champions, striking down a huge Egyptian with the man's own spear, and going down into a pit on a snowy day to kill a lion. Commanded the royal bodyguard, stayed loyal at Solomon's accession, and replaced Joab as commander of the army.
2 Samuel 23:20-231 Kings 1:38-401 Kings 2:29-35
Zadok
The two chief priestsDavid's two priests. Abiathar had escaped the massacre at Nob and joined David in the wilderness, carrying the ephod. Zadok's line came from Eleazar. At Solomon's accession Abiathar backed Adonijah and Zadok backed Solomon, and Abiathar was removed.
1 Samuel 22:20-232 Samuel 15:24-291 Kings 2:26-27
Hiram

2 Samuel 5:111 Kings 5:1-121 Kings 9:10-14
Shimei
Who cursed DavidA Benjamite of Saul's house who walked along the ridge cursing David and throwing stones as he fled from Absalom. Abishai offered to remove his head; David said to let him curse, since the LORD might have told him to.
2 Samuel 16:5-132 Samuel 19:16-231 Kings 2:8-9
Nebat
Jeroboam's fatherNamed almost every time his son is, in the recurring formula about the sins of Jeroboam the son of Nebat, who made Israel to sin. The phrase appears more than twenty times and functions as the standard by which the northern kings are measured.
1 Kings 11:261 Kings 15:342 Kings 17:21-22
Naboth
The vineyard ownerA man of Jezreel who refused to sell Ahab his ancestral vineyard, since the law treated family land as inalienable. Jezebel arranged false witnesses, had him stoned, and handed the land to her husband.
1 Kings 21:1-241 Samuel 8:14
Hadad
Kings of Aram and EdomA name borne by several foreign rulers, mostly Aramean kings of Damascus. Ben-hadad besieged Samaria; Hazael, whom Elisha wept over on foreseeing what he would do, seized the throne by smothering his master with a wet cloth and became Israel's most destructive enemy.
1 Kings 11:14-221 Kings 20:1-212 Kings 8:7-15
Maacah
Several of this nameA name borne by both men and women across the Old Testament. The best known is the queen mother, Abijah's wife and Asa's grandmother, whom Asa removed from her position because she had made an obscene image for Asherah. Another Maacah was the mother of Absalom, a foreign princess.
2 Samuel 3:31 Kings 15:132 Chronicles 15:16
Meshullam
Names of the priestly housesNames that recur constantly through Chronicles, Ezra, and Nehemiah, often carried by several different men, and usually attached to the priestly and Levitical families. They are among the most common Hebrew names of the period, which is why the text so often has to add a father's name to tell them apart.
1 Kings 12:22-24Ezra 2:59-63Ezra 8:15-20
